Height difference between two terrains

Hello everyone

Is there a way to find the height difference between two terrains (in my case it will be the same terrain, one before terrain regulating and one after)?

The attached picture is a good example of what information I am looking for. The colored areas indicate the height difference between the existing terrain and the regulated one.

I use Revit and just started using Dynamo. Any ideas, methods, including using other softwares than Revit are welcome.

Thanks in advanced :slight_smile:

I would suggest creating a grid of points, i.e. every 10 cm, from these points you should create vertical lines extruded in both directions (up & down).
From these lines can you get an intersection point for both surfaces.
From these points can you then get an Z-value difference between them, positive or negative.
Now you can assign a color from these points.

However, this is kinda re-inventing the wheel since this functionality/ output can already be generated by other software (Infraworks, If I remember correctly,for example)

Hi Daan

Thank you . It sounds like a place to start. :slight_smile:
